Fuel Pump

[andygill]

I bought my Traveller 6 weeks ago at the time there appeared to be a problem with the fuel pump (the car had been in storage for about 8 years). I cleaned the connections and my friend got it going for me.

From then on no problem at all until the weekend, where it started playing up again, and has got worse each time I've used the car. Each time if I tap the pump it start OK however I can only go a few hundered yards without it cutting out again.

If like me you know very little about Car DIY would you a) take it to a mechanic to have a look at or b) get a new pump and fit it.

Thanks for your continued help.

Personally I'd give it go a myself. You've got to start somewhere, part of the fun of owning Minor is getting your hands dirty every now and then and if you get stuck there's loads on people on here that can give you advice

Hi Andy,

The problem with the fuel pump is well known - and straightforward to cure. You can consider what I did - purchase a new pump, then repair the old one. That way the car is on the road - and there's no pressure to complete the repairs...

Inside the black plastic cap of the fuel pump is a set of contacts - these open and close as a metal rod pumps the fuel (indeed - the contacts make an electric circuit which energises an electromagnet - pulls the pump shaft down, then releases & repeats).

The contact set will erode over time and the cure is a replacement set (usually about £6).
All you do for replacement is:-
a) remove the pump form the car (not absolutely necessary - but much easier!)
b) remove the adhesive tape and the black plastic cover.
c) remove the black plastic top (two screws in the pedestals) - also removes the electric connections
d) unscrew the old contact set (count the turns!)
e) screw in the new set (same number of turns!)
f) replace the black plastic top (including the electrical connections)
g) set the gap at the top of the contacts to 10 thousandth's of an inch
h) Gap at bottom as 0.1 inch (I used a 2.3 mm drill as a slip gauge)
i) replace cover replace pump in car...

You'll find a digital camera invaluable - take lots of photos - much better than memory!

d) unscrew the old contact set (count the turns!)
e) screw in the new set (same number of turns!)

That's not really the recommended way to set the throw-over point. It might work if you're lucky but the new set may not have the same tolerances. The proper method is described in the workshop manual.

Certainly don't take it to a 'mechanic'! And If you buy a pump - DO NOT buy an electronic one ! The good old original points pumps are good for 40 years - and then they may need new points.............

Thanks Colin.

Where did you buy your pump from ? and how much ?

Cheers

With respect Josh I think Andy needs a new pump while he learns to strip/rebuild the old one. If he were to buy another second hand pump he may end up with the same problem. This way by fitting a new one he is "on the road" again

Hi,

Where did you buy your pump from ? and how much ?

ESM or Bull Motif - they sell new pumps (made by Burlen - who still make the SU fuel pump!)

Or you could always make an offer - mmjosh has one (s/hand) - I have a spare one as well - remember that P&P is going to add to the cost - they're heavy items....

I'd suggest that you look at the on-line suppliers for prices before you look at Ebay - I've seen the green indicator lens sell for £5 on ebay (plus P&P) - they're 99p from the suppliers!

Sometimes a good working used pump is the best bet........ That's the way I would go!
